Wi-Fi/Bluetooth
The module provides a shared antenna interface ANT_WIFI/BT for Wi-Fi and Bluetooth functions. The
interface impedance should be controlled to
50 Ω. You can connect external antennas such as PCB
antenna, sucker antenna, and ceramic antenna to the module via the interface to achieve Wi-Fi and
Bluetooth functions. Bluetooth and WLAN (both 5G and 2.4 G) are operating in TDD under coex mode.
4.1. Wi-Fi
